I'm trying to use the PKG_CHECK_MODULES macro to check for an external
library:

PKG_CHECK_MODULES([LIBUSB], [libusb-1.0], [have_libusb=yes],
[have_libusb=no])

This works great, except when trying to compile on a system without
pkg-config installed. The configure script fails with a syntax error. I
tried to wrap the PKG_CHECK_MODULES check in an AC_ARG_ENABLE enable block,
in an attempt to enable to skip this check. But this makes no difference.

Is there another way to make this work?

before any  PKG_CHECK_MODULES, call PKG_PROG_PKG_CONFIG to check if
pkg-config is available

I tried that, and it makes no difference.
